Hello,

as you have a KM184 already, the typical choices would be

- KM120, of the older KM100 system, dark gray,

- KM120A (consisting of KM-A output stage and KK120 capsule), nickel or nextel-black.

I would recommend the KM120A, being the current modular system, with improved self-noise and state-of-the-art circuitry.

Then, a pair of MS clips, or a double suspension will snap the mics on top of each other, and you have a very nice & practical MS setup.

Best regards,
